Orlando, in tn e county of @range end State of Floride., .have invented new and `nseiiul Improvements in. Shoeloibsorbersf which the following is e specification.

My invention relatesto shock absorbers for use' on automobiles. or other vehicles, -its mein object being to lorovide an eioient ded vieeI of simple construction which reedilyepplied' te the velliele, and Winch will absorb slioelis incident to compressions and reactions ofthe vehicle springs.

.notlier object of the invention is to provide ineens whereby the device may be reed-1 ily adjusted to suit the pertieuler vehicle te which it is applied.. u

TWith these objects in View, my inifentlon consists in the features hereinafter olesoribed and particularly pointed ont in the appended claims.l

Referring to the drevvings forming e part oft-his speeiiszetion; lligme. l is e top or Ulan View of e shook absorber embodying iny invention, and Fig. 2 is s partiel longitudinal vertical seetion thereoitl.

A and A indicate e pair of arms 'which are pivotally connected together et la?, the free ends a and a of seid arms being provided with apertures a, by Ineens of which one of seid arms may be secured in any suitable manner to the body of e vehicle, und the other to some .convenient part ol the vehicle running gear; orltlie device may be applied to the yeliiele springs in any man ner best suited to resist er retard violent reooils thereof; and as will be hereinafter' explained, said device may, if desired, be adjusted to also resist eompressions of the springs.

lt will oe understood that when properly' mountecL the free ends of tlie amis A and fi Will lie mo/ecl toward and from each other by movements of the vehicle body due to compression and expansion of the vehicle springs, and to resist relative movement of said firms,V l lieve provided a device which is carried by the pivot-el Connection said device somprisinge, reciprocating member B and means for resisting nio-vement liereof. The particular means for resisting movenient of the menilier B .is immaterial to the brood ideeoi mounti. movement resisting on the p tsl connection or" tire arms Y. ,.lustrated in the specification of Letters ratei-m..

Longitudinal passages c and Ao2 are provided in, opposite' wells of the eylim der C, said passages being in free communication with one end of the, cylinder through ports c3 and el, and comme eating with the opposite end the cylinder tlirou l1 velved ports ci and e. ,.llie port 'die norme lyelosed by e valve J which is held to its seat. l3y=- e, spirali spring Q52 mounted on the valve-seem d3' endoperating between e ledge di surrounding the di, edjustebly mounted en the valve-stenenuts e36, thelater being sciesv threeded'on the valve-stem, es will be readily understood. The valve-stem, spring and adjusting; nuts, ere housed in of the cylinder C which is provided with e removable sep or plug lf, so that eccessmey be had to the valve adjusting means, for purposes hereinafter described.

The port e is controlled by e valve e opening outwardly and which .is normally held to its seat by e spring e2 pressing against the heeded valve-stem e3.

end spring' is inelosed in n. liollovv es@ tension lf2 of the cylinder C5 said extension being provided with e removable cap or plug f3. The tension of the spring e2 is regulated bymeans of e Screw f* tapped through the plugf3 disk e* which in turn end or the sprinff.

The reciprocating member B has its outer und )ivotelly connected totwo links G and G", tlie link G' having its outer end pix-Totally connected to e sleeve H adjustably mounted on the erm A, and the link G having its outer end similarly connected to :i sleeve El mliustably mounted on the erm A. The sleeves ll and H :ire slideole on the arms A mid Il', and are looked in any desired position thereon by set T bears against the outer screws 71,. lie links Gr and G are each rendered adjustable es to length by constructing them in` two joel-ts' g and g', the part g being provided with e screw-threaded stem g2 iitting into an inte.; riorly-tlireaded socket in the part 57.

G. and Gf, and the adjiistment of their pivetal connection-With the arms A and A', are provided to enable the reciprocating member B to be properly adjusted vwith reference to the, cylinder (i, at any desired normal position ofthe arms A and A.- In other words, the desired normal angle of the armsV A and, A"1nay be` increased 0rdiminished to suit particular requirements, by adjusting the connections with the reciprocating member B, so that the latter may be proparly positioned with respect to the cylinder C or other movement resisting element.

' lhe cylinder C lis designed to beiiilled vwith glycerin 'or other liquid, or with 'air only, and it will be understood that when the device is properly mounted,'as hereinbefore described, compression of the vehicle springs will cause the outer ends of the arms and A. to move toward each other. The reciprocating member B will be thereby drawn outwardly from the cylinder C by the links G and Gr acting as a toggle lever. The. liquid or Huid in the forward end' of the 'cyiinder` C will be forced by the piston b ,through port c3 and passage c to the other side of the piston through the port d, the

passage of the liquidthroughsaid port being 'Y l,more or less retarded by the Va1ve'd,according to the adjustment of its spring d. On

the rebound or, recoil of the vehicle spring, the arms A and A Will bemoved apart, and

resistance to" .this movement will be oi'ered .bythe fluid at the rear of the piston, which will be slowly forced by the piston through the port c, passage c2 and port c4 to the front of the'cylinder'.- The passage of the iiuid thrcughzport e will be resisted by the preslit" sure'oflspring e2 Aon the valve c, which, as

will befjrcadily understood may be adjusted I to snit;'requicrements.ty

rv When the device vis initial] mounted :on a vehicle, the. links G and f are disconv neoted from ythe reciprocatingfiember andtheir 4length and connectionywith thev arms A and A vadjustr-zd to properly position the piston b in the. cylinder C with respect to the normal angular position of said arms, said links being thereafter connected to tle member B, aswill be readily understoo 1` Having thus described my imention, what 'I claim-.as new and Ldesire to secure by L'etters 4'.Patent is,

l. In a shock absorber, the combination of a pair of pivotally connected arms', a pivot support adjustably mounted oneach of said arms, a movement retaiding device supported by said arms at their pivotal connection, said device including a reciprocating member and means for resisting movement thereof, and a pair of links pivotally connected at one end to said reciprocating member, each of said links being'pivotally connected at its other end to one of said piyot supports. 2.
